MACHINE FOR LINING STRAW-BOARD.

SPECIFICATION forming part of Letters Patent No. 226,733, dated April20, 1880.

Application filed March 3, 1880.

To all whom it may concern:

Be it known that I, GEoRG'E S. EYs'rEE, of Halltown, in the county ofJefferson and State of West Virginia, have invented certain new anduseful Improvements in Machines for Lining Straw-Board; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, which form a part ofthis specication, and inwhich- Figure 1 is a side elevation. Fig. 2 is a ver tical longitudinalsection through the middle line of the machine. Fig. 3 is a similarsection through one side of the machine, (parallel to the sectionrepresented in the foregoing tigure,) showing the arrangement ofthedevice for regulating and adjusting the tension of the upper or tensionroller; and Fig. I is a detail view of the device for adjusting andregulating the position of the blue-paper roll in respect of the upperroll or tension-roller.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to that class of machines which are employedfor lining continuous lengths of straw-board or other analogous materialwith thin paper or textile fabric; and it consists in the constructionand arrangement of parts of a machine adapted to line both sides of thestraw-board simultaneously and at one operation-for example, applyingwhite lining-paper to one side and blue paper to the otherside-substantially as hereinafter more fully set forth.

In the Letters Patent of the United States No. 221,403, granted to me onthe 11th day of November, 1879, I have shown and described a machine forlining a continuous web of strawboard with a continuous web oflining-paper on one side by first applying a thin film ofl paste to thatsidel of the straw-board which is to receive the lining, and thenuniting the pastecoated board and dry lining-paper by tension, incontradistinction to effecting the union by passing the board and paperbetween two or more pressure or uniting rolls.

In the machine which forms the subject of my present invention I employthe same prin- Veiple; but instead of applying the paste to one (Nomodel.)

side of the board only I apply a thin film of paste upon both sidesthatis, tirst on one side, which then receives itslining, after which thelined board is pasted ou its unlined side and the second lining applied,which, with the exception of drying this doubly-lined board, completesthe operation.

In the two sheets of drawings hereto aunexed, A represents the bed ofthe machine,

the standards a a of which support an upper frame, A', in which thewhite-paper rolls B B are journaled, their journals being provided withadjustable resistance or friction blocks to provide for the propertension of the paper as it is being wound off.

rlwo pastefvats, C D, are employed, arranged parallel to but one alittle above the other, each of which has its appropriate paste-roller EF and distributing-roller E' F', each of which said distributing-rollersis covered, as usual, with ajacket, c j'.

The several rolls or rollers E E' F F' are provided withsuitably-arranged intermeshing gear-wheels, and one of them should yhavea drum or pulley, so that the whole set or series may be run by a singlebelt, if desired, revolving as plainly, indicated by the arrows in Fig.l. Each of the distributing-rollers E' F' is adapted to be adjusted inits boxing with reference to its paste-roller, to regulate the supply ofpaste which it is to receive from the lel arms, b, each ot which ispivoted in the upper end of an upright, c, of which there is one on eachside of the machine, opposite to each other. In the free end of one (orboth) of said pivoted arms b is hinged a rod, d,the lower end ofv whichis pivoted in a crank, g, at one (or both) end of a rock-shaft, I, whichsaid rock-shaft is provided with a projecting arm or lever, I', the freeend of which may beadjusted by means of a set-screw, h, bearing againstit from the under side in such a manner that lever I' is free to move inan upward direction, while it is prevented from moving down ward by thebifurcated head of set-screw h, in which it rests. It follows that byoperating the said' set-screw the upper roller, G, may be adjusted inits relation to E'-that is, the dis- IOO tance between the two rollersE' G may b'e regulated at will for the purpose of regulating the supplyof paste. After this adjustment has, however', been properly effected inthe manner described, or byequivalent means, the said rollers E G are toremain in their relative positions during the operation or run ot' themachine.

In like manner and by a similar arrangement of pivoted arms supportingits axle, a connecting rod or rods, and a crank-shaft provided with alever arm, the adjustment of which is effected by a set-screw, mayroller H be adj usted in relation toits co-operating roller F 5 and, ifdesired, these adjusting devices may be so constructed and connectedthat the operation of one affects the other, so that by adjusting rollerG roller H is adjusted to the same extent, or vice versa.

If desired, the said upper rollers, G H, may

be provided with cog-wheelsthat mesh with the gear-wheels on rollers Eand F', respectively, which does not interfere with the function of saidupper or tension rollers, and under certain circumstances proves veryefficacious.`

The proper adjustment of the several rolls having been effected, thestraw-board is fed between rollers E G, as shown in Fig` 2, by passingit over suitably-arranged guide-rollers L M. In its passage betweenrollers E G, the side facing roller E', it is coated with a thin lm ofpaste, and is then doubled around Athe.' tension-roller G, where itmeets the blue paper X, which is fed from the blue-paper roll N up overroller G, where it comes in contact with and is united byits tension tothe pastecoated sidel of the straw-board. The bluelined board nowtravels, in the direction of the arrow, in between the next pair ofrollers, F H, where the unlined side of the board receives a film ofpaste, after which it is doubled around roller H, where it meets thewhite lining-paper Y from the white-paper roll over the rolls J K, andis united thereto simply by the tension of the white paper over rollerH, and without the aid of spreading-rolls, pressurerolls, orsimilarcontrivances of any sort. The board, which is .now lined 011 bothsides, next passes over rolls O P, set at different elevations, and overa series ofI drying cylinders, where the double-lined straw-board isthoroughly dried and ijnished.

The blue paper feed-rollNshould be made adjustable in a plane parallelto that ofthe axis of roller G-that is, transversely to the bed or frameof the machine, which can be effected in different ways. I prefer to usethe arrangement shown more clearly in Fig. 4 ou Sheet 2 of the drawings,which consists simply of a dovetailed bar, Q, placed transversely acrossthe frame and sliding between dovetailed guide-bars, or in a dovetailedplate, It. Bar Q has an upright, S,

at each end, between which the blue-paper roll N is hung, and thesliding bar may be adjusted by means of a set-screw, T, working througha collar secured on one side of the machineframe, so that by simplyturning this screw the position of the blue-paper roll relative to thetension-roll G may be effected with great nicety and accuracy, thussmoothing out wrinkles in the lining-paper and counteracting the effectof untrue or uneven winding of the paper upon its roll from which itis-fed. 4

It will be seen, on comparison of this machine with the lining-machinefor which Letters Patent were granted to me on November l1, 1879, No.221,403, that it is substantially the same machine, with the addition ofthe paste-vat C and rollers E E G, or, considering these as parts of theold machine, with the addition of the vat D and its rollers F F H.Hence, simply by adding this extra set of rolls with their vat to theold machine,this is transformed into a double-lining machine Withoutotherwise disturbing or affecting its operative parts.

The advantages of a machine adapted to line straw-board and analogousmaterial oli both sides by a single operation will readilyA beappreciated without further explanation. It saves time, labor, andmoney, and produces a better and more merchantable article ofmanufacture than board which is lined upon one side only, or lined in acontinuous web upon one side by machinery only, and then cut up insheets which are lined each separately on the other side by hand.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- 1. A machine for lining acontinuous web of straw-board or analogous material upon both sides by asingle operation without the use of pressure or compressing rolls,substantially as set forth.

2. The process of lining a continuous web of straw-board or analogousmaterial upon both sides and by a single operation with two continuouswebs of dry facing or lining paper, one for each side, by uniting eachsheet or web of dry lining-paper to its respective pastecoated side ofthe board to be lined by stretching the board successively over tworolls arranged parallel to each other but at different elevations, andthen stretchingor passing one of the webs of lining-paper over one ofthese rolls and the second web of lining-paper over the second roll,both webs being in a state of tension, and united to their respectivesides of the paste-coated board by such tension and without the use ofco-operating pressure or uniting rolls, substantially as set forth.

3. In a machine or apparatus for lining straw-board or analogousmaterial, two pasterollers mounted in parallel planes and each operatingin conjunction with a distributingroller, in combination with a pair oftensionrollers operating in conjunction with the saiddistributing-rollers, one of which said tensionrollers operates, first,to feed the continuous web of board against the paste-coated surface ofits co-operatin g distributing-roller, where it (the board) receives athin film of paste; and
